Thanks so much for taking the time to go into detail. I just followed your advice and found that I could not replace the user name on the prompt, so I ran it to the end and modified the app.yml file to hold an empty string (“”) in that field. Unfortunately, I could not verify that these setting would work for me because, when I tried to build it, the script complained that my Docker 1.7 was not sufficient, that I needed 1.8 or better. When I tried to update I was informed that my kernel was not 3.10 and I could not install the latest Docker. So I am off to figure out how to either get Docker 1.8, or manually install Discourse from packages & sources (shudder!) or get my hosting provider to upgrade my CentOS 6.8 to something newer, which may or may not work. I really wish the “easy” instructions would include a link to the full requirements so that I could check them all off before even starting. This is like being fed ingredients one at a time and running to the store to buy item, only to have the next ingredient revealed once you try again! 🙂 But that’s not your issue, thanks for this valuable info and I’ll test it in detail once I solve these other problems. Maybe I should jump into trying to do a full install from packages & source, etc. --- _[View the full topic](https://meta.discourse.org/t/how-to-determine-smtp-setting-from-exim/53941)._
